TRAP_CAUSE_UNKNOWN

STOP: 0x00000012

Description

An unknown processor exception occurred. While rare, it might indicate issue from an older Windows OS that doesn't know about the latest processor exceptions with the latest CPUs.

This is a fatal Windows error, typically called a Stop message, Bug Check, or more commonly the Blue Screen of Death (BSoD). The system is in a forced reboot state. Any unsaved work is likely lost.

Sample Screen

A problem has been detected and Windows has been shut down to prevent damage to your computer.

TRAP_CAUSE_UNKNOWN

If this is the first time you've seen this Stop error screen, restart your computer. If this screen appears again, follow these steps:

Check to make sure any new hardware or software is properly installed. If this is a new installation, ask your hardware or software manufacturer for any Windows updates you might need.

If problems continue, disable or remove any newly installed hardware or software. Disable BIOS memory options such as caching or shadowing. If you need to use Safe Mode to remove or disable components, restart your computer, press F8 to select Advanced Startup Options, and then select Safe Mode.
